项目摘要

(1) Pen-Based Drawing System for Geometric Design:We proposed two novel interaction techniques called "interactive beautification" and "predictive drawing." Interactive beautification receives the user's free stroke input and generates multiple candidates by considering possible geometric constraints. Predictive drawing shows next drawing operation based on the spatial relationship among existing figures. We then developed a prototype system Pegasus, and achieved fast and flexible drawing interactions.(2) Pen-Based Sketching Interface for 3D Freeform Design :We developed a pen-based drawing system "Teddy", a sketching interface for creating 3D polygonal surface models. The user can create a 3D model by drawing 2D silhouette with a pen. Our informal user study showed that a first-time user typically masters the operations within 10 minutes, and can construct 3D models within minutes. This papers was awarded Impact Paper at SIGGRAPH'99.(3) Context-aware information system for mobile computer :We proposed a new information system architecture called the "WEBPAD system". WEBPAD is attempts to be a general-purpose context-aware UI system, which recognizes and predicts current user's "context" information. Our system employs thin-client technique to offload much of the data processing to the server. The server collects useful information from the WWW automatically. The user can create new information via a camera and a microphone, and the information is distributed to others via information filtering techniques.(4) Multiple Painting Input System :We developed a prototype system of multiple pointing input system. Our system recognizes multiple movements of devices that is moved by a user simultaneously, so the user can point and manipulate multiple object on the screen.

(1)基于笔的几何设计绘图系统：我们提出了两种新的交互技术，称为“交互美化”和“预测绘图”。交互式美化接收用户的自由笔画输入，并通过考虑可能的几何约束来生成多个候选笔画。预测绘图根据现有图形之间的空间关系显示下一个绘图操作。然后，我们开发了一个原型系统Pegasus，并实现了快速和灵活的绘图交互。(2)用于3D自由设计的笔式草图界面：我们开发了一个基于笔的绘图系统“Teddy”，一个用于创建3D多边形表面模型的草图界面。用户可以通过用笔绘制2D轮廓来创建3D模型。我们的非正式用户研究表明，首次使用的用户通常在10分钟内掌握操作，并可以在几分钟内构建3D模型。该论文在SIGGRAPH'99上获得了影响论文奖。(3)移动的计算机的上下文感知信息系统：我们提出了一个新的信息系统架构称为“WEBPAD系统”。WEBPAD试图成为一个通用的上下文感知UI系统，它识别和预测当前用户的“上下文”信息。我们的系统采用了瘦客户端技术，将大部分数据处理工作转移到服务器上。服务器自动从WWW收集有用的信息。用户可以通过摄像头和麦克风创建新的信息，并通过信息过滤技术将信息分发给其他人。(4)多画面输入系统：我们开发了一个多指向输入系统的原型系统。我们的系统可以识别用户同时移动的设备的多个移动，因此用户可以指向和操纵屏幕上的多个对象。
